Controlled self-ignition combustion process and associated four-stroke engine with transfer line between cylinders and dedicated value

摘要

The present invention relates to a controlled self-ignition combustion process in a four-stroke engine having plural cylinders (1) having each at least a first intake (2) and at least a first exhaust (3). The process according to the invention during partial load operation, transfers, via at least one additional port (4) of each cylinder and an exhaust gas transfer, exhaust gases from a cylinder in the exhaust phase to another cylinder in the intake phase. The present invention further relates to a multicylinder four-stroke engine working on controlled self-ignition, allowing implementation of the above-described process.
